Windmill power is proportional to V cubed.
Same as power required to push a car through the wind.
Car that takes 20hp to go 60 mph, takes 160hp to 120 mph.
"Windmill power is proportional to V cubed."Nah. Look at #1375 a little closer.
It's simple, so drag =1 there. Air is compressible, so real drag is < 1.
Only supersonic shock waves have v3.
